The front 29 walls and means for facilitating flexing of of the tray has secured thereto in alny suitable the wal1s to remove the contents. A suitable manner a handle 31.

removed therefrom without disturbing the In Fig. 3 I have shown one manner in others. which each -receptacle can be supported by Referring now to the drawing, I have the tray 26. In this form of the device, the wo shown a cup shaped receptacle 16 having a dimensions of each aperture 32 am such that the receptacle will be supported by engagementof an intermediate portion of the side Walls 17 with the tray. The receptacle can be removed by lifting the same by rim 18 or by pushing against the base 19.

In order to preclude wedging of the receptacle in the supporting tray due to expansion of the con tents or other causes, each of the apertures in the tray can have a peripheral edge 33 which is bent downwardly, as shown in Fig. 4. In 1}his embodiment expansion of the contents while freezing causes the along the sides of the receptacle f01: a short distance so that it will engage the tray near the periphery of the aperture 32 when inserted therein. In this embodiment, als0, the apert-ure 32 is preferably made large enough to allow for expansion.

By reason of the separate supports for each of the individual receptacles, any desired number of receptacles can be withdrawn 01' replaced at any time without di sturbing the o ther receptacles in the tray. Each receptacle can be emptied separately merly by fnrcing the rim and base of the receptacle toward each other by the thumb and fingers of one band and the shape of the solidified contents need not be destroyed. It is to be understood that the rece1utacle can have any des'ired cross sectiona1 shape and it need n ot be circular as illustrated in the drawing.

The receptacle which I have described is suitable for wide variety of uses and can be utilized for frozen substances, such as ordinary ice 01 ice cream and also for substances which are adapted to sei; er solidify without freezing, such as gelatinous 01' coagulabed. products.

While I have shown and described certaiin preferred embodiments of my invention, I d0 not Wish to be limited thereto, since the invention as defined in the appended claims can be embodied in a plurality of other forms.

I claim:

1. A cup shaped receptacle for liquids to be solidified, resilient side walls in said receptacle and a relatively rigid rim adjacent the mouth of said receptacle, said side walls being collapsible by a force exerted against said rims, and tabs projecting from said rim for facilitating the application of said force.

2. A cup shaped receptacle for liquids to and a relatively be solidified, resilient side Walls in said receptacle and a reinforced rim adjacentthe mouth of said receptacle, said side Walls being tapered from the mouth of the receptacle toward the base 0f the same thereby permitting said side- Walls t0 be flexed by a force tending to move said rim toward the base of the receptacle, and tabs projecting from said rim for facilitating thenpplication of said force.

3. A receptacle for liquids to be solidified, said recepigacle having relatively resilient side Walls, a relatively rigid base, and a relatively rigid rim adjacent the mouth of the receptacle, said side Walls being collapsible by a compressional force applied against said rim and said base to remove the contents of said receptacle, and tabs projecting from said rim f0r facilitating the application of said force.

4. A rubber cup suitable for liquids to be solidified, said cup having a'relatively thin flexible side Wall, a relatively thick base, and a relatively thick rim adjacent the mouth of the cup, said side Walls adapted 130 be flexed 130 remove the contents 0f said cup by a compressional force applied against said rim.and said base, reinforcihg means in said rim and projections extending from said rim t0 facilitate the application of said force.

5. A rubber cup suitable for liquids to be s'olidified, said cup having relatively t-hi n flexible side Walls, a relatively thick base thick rim adjacent the mouth 0f the cup, said side walls being c01 lapsible to rernove the contents 01 said culo by a compressional force applied against said rim and said base, and finger engaging tabs on said rim for aflording convenient applicev tion 0f said force by the fingers and thumb 0f one band of a user.

In testimony whereof I have hereunto set my hand.
